Answer:
it's density is 8 g /cm³
Step-by-step explanation:
Mass (m) = 96 g
Volume (v) = 12 cm³
Density (d) =?
We know density is defined as mass per unit volume so
d = m/v
= 96 / 12
= 8 g/cm³
Hope it will help :)
Note : if in the question it is said to write in sI system u have to write in kg/m³.
Answer:
Isosceles
Step-by-step explanation:
Consider triangle ABC, BD is the median and the altitude drawn to the side AC. This segment (BD) divide the triangle ABC into two triangles: ABD and CBD.
In these triangles:
- AD=DC (because BD is the median);
- ∠ADB=∠CDB=90° (because BD is the altitude);
- BD is common side.
Thus, by SAS postulate, triangles ABD and CBD are conruent. Congruent triangles have congruent corresponding sides. Hence, AB=CB.
If in triangle ABC, AB=BC, then this triangle is isosceles.
